2 Nephi 2

What will protect you from the sin and evil around you? I maintain that a strong testimony of our Savior and of His gospel will help see you through to safety. If you have not read the Book of Mormon, read it. I will not ask for a show of hands. If you do so prayerfully and with a sincere desire to know the truth, the Holy Ghost will manifest its truth to you. If it is true—and it is—then Joseph Smith was a prophet who saw God the Father and His Son, Jesus Christ. The Church is true. If you do not already have a testimony of these things, do that which is necessary to obtain one. It is essential for you to have your own testimony, for the testimonies of others will carry you only so far. Once obtained, a testimony needs to be kept vital and alive through obedience to the commandments of God and through regular prayer and scripture study. Attend church. You young men, attend seminary or institute if such is available to you. (“Priesthood Power,” Ensign, May 2011)
